fc5606ff19 Now that enough bugs are fixed :), mark more things as immutable values: 
- foreach enumerators
- closure arguments with explicit patterns
- 'value' in a setter
- subscript arguments

71af72a0ca Change a few more kinds of arguments to be 'var' arguments instead of 'let' 
arguments.  Until we have @inout methods on structs, we can't mark anything
that can be address-exposed.  This temporarily regresses a few testcases,
but they will come back later.

b1a2059604 Implement the ability to create a Pattern as a set of 'let' decls instead of 
var decls.  I was originally intending to use this for argument lists, but I
don't think that's a great direction to go anymore.

In any case, it seems uncontroversial to enforce immutability on foreach
enumation patterns, so I did that (see testcase)

8b11158753 Parser: Allow static vars in DisallowStoredVar contexts. 
The contexts for which we set the DisallowStoredVar bit, currently enums and extensions, can both (theoretically) support static variables, so change PD_DisallowStoredVar to PD_DisallowStoredInstanceVar, and allow static vars to be declared in these contexts.

54524e622a Replace ExprStmtOrDecl with ASTNode and make it a struct. 
Previously, the Parser and BranchStmt typedef-ed ExprStmtOrDecl as a pointer union. Using typedef made the objects compatible, but did not allow us to extend the type with helper methods, such as getSourceRange(), which is something you can get on all of the AST objects. This patch introduces ASTNode that subclasses from PointerUnion and is used by both parser and BranchStmt.

74ba1e8851 [Parser] In Parser::parseBraceItemList, when we don't find a right brace recover by using the PreviousLoc. 
This ensures that the brace range will include all contained items.
The previous scheme of choosing the end location of the last item was not accurate because for pattern bindings decls
we also push the var decls as items, but they don't have the full source range of the pattern binding decl.

Fixes rdar://15190792.

e05c03d5bc Standardize terminology for "computed", "stored", "variable", and "property". 
These are the terms sent out in the proposal last week and described in
StoredAndComputedVariables.rst.

variable
  anything declared with 'var'
member variable
  a variable inside a nominal type (may be an instance variable or not)
property
  another term for "member variable"
computed variable
  a variable with a custom getter or setter
stored variable
  a variable with backing storage; any non-computed variable

These terms pre-exist in SIL and IRGen, so I only attempted to solidify
their definitions. Other than the use of "field" for "tuple element",
none of these should be exposed to users.

field
  a tuple element, or
  the underlying storage for a stored variable in a struct or class
physical
  describes an entity whose value can be accessed directly
logical
  describes an entity whose value must be accessed through some accessor
